如何从 LineString 未排序列表创建多边形
How to create Polygons from LineString unsorted list
我有 geojson 文件。此文件包含 LineString 列表。我想从此列表创建多边形。但是每个 LineString 都是一个特征，我不知道哪个 LineString 创建了具体的多边形。注意 - 文件包含不创建多边形的 LineString。
如何从 Python 中的此列表创建多边形？
谢谢

您可以尝试使用 polygonize。这将创建由线串包围的多边形。
import geopandas
from shapely.ops import polygonize
gdf = geopandas.GeoDataFrame.from_features(f)
polygons = geopandas.GeoSeries(polygonize(gdf.geometry))
polygons.plot()

您可以尝试使用 polygonize。这将创建由线串包围的多边形。

from shapely.ops import polygonize
gdf = geopandas.GeoDataFrame.from_features(f)
polygons = geopandas.GeoSeries(polygonize(gdf.geometry))
polygons.plot()
